Travel storage system, travel storage method, and video recording system

Abstract

A travel storage system includes: a target vehicle behavior determination unit that is configured to: acquire a sensor value indicative of a behavior of each of surrounding vehicles around the host vehicle; and sequentially determine a relative behavior of a target vehicle with respect to the host vehicle based on the sensor value; a rule acquisition unit that acquires an accident liability rule in a current position of the host vehicle; a potential accident liability information determination unit that sequentially determines, using liability determination information, potential accident liability information indicative of whether the host vehicle is liable for a potentially assumed accident between the target vehicle and the host vehicle; and a storage unit that stores the potential accident liability information and the liability determination information in association with each other or in associable with each other.

1 . A potential accident liability determination device, comprising:
 a liability determination information acquisition unit configured to acquire liability determination information being information used to determine potential accident liability information indicating whether a liability determination vehicle being a vehicle for which the potential accident liability information is determined is liable for a potentially assumed accident between the liability determination vehicle and a target vehicle selected from surrounding vehicles existing around the liability determination vehicle; and   a potential accident liability information determination unit configured to determine the potential accident liability information based on (i) a preset relationship for determining the potential accident liability information from the liability determination information and (ii) the liability determination information acquired by the liability determination information acquisition unit, wherein   the potential accident liability determination device is installed outside of the liability determination vehicle.   
     
     
         2 . The potential accident liability determination device according to  claim 1 , wherein
 the liability determination information acquisition unit is configured to acquire, as the liability determination information, a sensor value that is detected by a sensor provided in the liability determination vehicle and indicates a behavior of the peripheral vehicle,   the potential accident liability determination device further comprises:
 a target vehicle behavior determination unit that is configured to sequentially determine, based on the sensor value, a relative behavior of the target vehicle selected from the surrounding vehicles with respect to the liability determination vehicle; and 
 a rule acquisition unit configured to acquire an accident liability rule at a position where the potential accident liability information is determined, and 
   the potential accident liability information determination unit is configured to sequentially determine the potential accident liability information based on the relative behavior of the target vehicle and the accident liability rule acquired by the rule acquisition unit.   
     
     
         3 . The potential accident liability determination device according to  claim 1 , wherein
 the liability determination information acquisition unit is configured to acquire a relative behavior of the target vehicle as the liability determination information, and   the potential accident liability information determination unit is configured to sequentially determine the potential accident liability information based on the relative behavior of the target vehicle and an accident liability rule at a position where the potential accident liability information is determined.   
     
     
         4 . The potential accident liability determination device according to  claim 1 , wherein
 the liability determination information acquisition unit is configured to acquire the liability determination information from each peripheral vehicle existing around the liability determination vehicle.   
     
     
         5 . A potential accident liability determination device, comprising:
 at least one processor; and   at least one memory storing computer readable program code, wherein   the computer readable program code, when executed by the at least one processor, causes the potential accident liability determination device to:
 acquire liability determination information being information used to determine potential accident liability information indicating whether a liability determination vehicle being a vehicle for which the potential accident liability information is determined is liable for a potentially assumed accident between the liability determination vehicle and a target vehicle selected from surrounding vehicles existing around the liability determination vehicle; and 
 determine the potential accident liability information based on (i) a preset relationship for determining the potential accident liability information from the liability determination information and (ii) the acquired liability determination information, wherein 
   the potential accident liability determination device is installed outside of the liability determination vehicle.   
     
     
         6 . The potential accident liability determination device according to  claim 5 , wherein
 the computer readable program code further causes the potential accident liability determination device to:
 acquire, as the liability determination information, a sensor value that is detected by a sensor provided in the liability determination vehicle and indicates a behavior of the peripheral vehicle; 
 sequentially determine, based on the sensor value, a relative behavior of the target vehicle selected from the surrounding vehicles with respect to the liability determination vehicle; 
 acquire an accident liability rule at a position where the potential accident liability information is determined; and 
 sequentially determine the potential accident liability information based on the relative behavior of the target vehicle and the acquired accident liability rule. 
   
     
     
         7 . The potential accident liability determination device according to  claim 5 , wherein
 the computer readable program code further causes the potential accident liability determination device to:
 acquire a relative behavior of the target vehicle as the liability determination information; and 
 sequentially determine the potential accident liability information based on the relative behavior of the target vehicle and an accident liability rule at a position where the potential accident liability information is determined. 
   
     
     
         8 . The potential accident liability determination device according to  claim 5 , wherein
 the computer readable program code further causes the potential accident liability determination device to acquire the liability determination information from each peripheral vehicle existing around the liability determination vehicle.
